<P align="left" style="font-size: 10pt">Trustee and Plan Participants<BR>
Mesa Air Group, Inc. 401(k) Plan<BR>
Phoenix, Arizona

<P align="left" style="font-size: 10pt">We have audited the accompanying statements of net assets available for benefits of Mesa Air Group,
Inc. 401(k) Plan (the &#147;Plan&#148;) as of September&nbsp;30, 2004 and 2003, and the related statements of
changes in net assets available for benefits for the years then ended. These financial statements
are the responsibility of the Plan&#146;s management. Our responsibility is to express an opinion on
these financial statements based on our audits.


<P align="left" style="font-size: 10pt">We conducted our audits in accordance with standards of the Public Company Accounting Oversight
Board (United States). Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material misstatement. The
Plan is not required to have, nor were we engaged to perform, an audit of its internal control over
financial reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the circumstances, but
not for the purpose of expressing an opinion on the effectiveness of the Plan&#146;s internal control
over financial reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates made by management,
as well as evaluating the overall financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.


<P align="left" style="font-size: 10pt">In our opinion, such financial statements present fairly, in all material respects, the net assets
available for benefits of the Plan as of September&nbsp;30, 2004 and 2003, and the changes in net assets
available for benefits for the years then ended in conformity with accounting principles generally
accepted in the United States of America.


<P align="left" style="font-size: 10pt">Our audits were conducted for the purpose of forming an opinion on the basic financial statements
taken as a whole. The supplemental schedule listed in the table of contents is presented for the
purpose of additional analysis and is not a required part of the basic financial statements, but is
supplementary information required by the Department of Labor&#146;s Rules and Regulations for Reporting
and Disclosure under the Employee Retirement Income Security Act of 1974. The schedule is the
responsibility of the Plan&#146;s management. The schedule has been subjected to the auditing procedures
applied in our audit of the basic 2004 financial statements and, in our opinion, is fairly stated
in all material respects when considered in relation to the basic financial statements taken as a
whole.

accounting principles generally accepted in the United States of America requires the Plan

assets available for benefits and changes therein, and disclosure of contingent assets and
liabilities. Actual results could differ from those estimates. The Plan utilizes various
investment instruments, including mutual funds and investment contracts. Investment
securities, in general, are exposed to various risks, such as interest rate, credit and
overall market volatility. Due to the level of risk associated with certain investment
securities, it is reasonably possible that changes in the values of investment securities
will occur in the near term and that such changes could materially affect the amounts
reported in the financial statements.</TD>
